I have the following audio gear:
- Shure FP33 3 Channel Mixer
- M-Audio Axiom 25
- 4 Channel Desktop Mixer w XLR inputs, mono output (large), runs on 12 C batts/AC
That's a good question, goldfi. I know you can plug an extenal power adapter into it. I've always used it plugged into my computer. I know it can also be used to control any external midi devices (ie Kurzweil keyboards, etc.) Looking at unit, it seems to lack a headphone jack, so my guess would be no -- you need to an external midi device to produce the sound, the axiom's just a controller.
